Auburn is the Placer County seat and one of the oldest towns in our service area, with a genuinely historic core around Old Town and the Auburn Courthouse alongside newer subdivisions built into the surrounding foothills from the 1990s onward. The older core carries the same mixed-era plumbing history as Placerville, original iron, mid-century patches, and everything since. The newer foothill developments run standard copper and PEX.
What connects both eras is the terrain: Auburn sits at a meaningful elevation change from the valley floor, which affects water pressure and sewer lateral grade on both old and new properties alike. We factor elevation into pressure diagnosis here more than we would on a flatter site like Roseville or Rocklin.
